The death of Persephone was a big blow to everyone.  For one thing, she always seemed not immortal but not mortal either.  So for her to actually die was a surprise.  It also put some urgency back into the search for Maura and Glendower.  I think her death will have more impact in The Raven King.  1. The triumvirate of Maura, Calla, Persephone has irrevocably been broken up.   The power of the number 3 is brought up many times in Blue Lily Lily Blue.  The three of them often talk about how their powers are the strongest together.  How will they be now that she is gone?  Persephone also talked about possibly having Adam one day replacing one of them but never says who.  She dismisses this notion but did she know that her time was short?  Who will step up to take her place and be Maura and Calla’s third?  Adam?  Blue? Gwenllian? Artemus?
